Thunderbolt 3/USB-C Adapters, Cables, and Hubs for New MacBook Pro
Thunderbolt 3 carries power, USB, DisplayPort, HDMI, and VGA over a single USB-C port, creating one standard for connecting most accessories and peripherals.
The issue for now, however, is not all devices are equipped with USB-C ports. Apple's very own iOS devices, for example, use a proprietary Lightning port instead.
More USB-C accessories will inevitably be released over the coming months and years, but in the meantime, many new MacBook Pro users will need to purchase at least one dongle or hub to use the notebook with their current setup. Own an iPhone? You need a new cable. Own a Thunderbolt Display? You need an adapter.
Below, we have rounded up some of the USB-C adapters and cables available from Apple and third-party accessory makers.
This adapter can be used to connect the new MacBook Pro to Thunderbolt or Thunderbolt 2 peripherals. Examples include Apple's discontinued Thunderbolt Display and older Thunderbolt external storage drives.
The adapter can also be used to connect the new MacBook Pro to Apple's Thunderbolt to Gigabit Ethernet Adapter and Thunderbolt to FireWire Adapter. Tip: Belkin sells a direct USB-C to Gigabit Ethernet adapter for $34.95.
The adapter is bidirectional, so it can be used reversely to connect new Thunderbolt 3 devices to an older Mac with a Thunderbolt or Thunderbolt 2 port.
USB-C Charge Cable — $25
Have you ordered a new MacBook Pro and also own an iPhone? You can't connect the two devices out of the box without purchasing an additional adapter or cable. One of those options is Apple's own USB-C to Lightning cable.
The cable can be used to charge and sync any Lightning-equipped iPhone, iPad, or iPod touch with USB-C devices like the new MacBook Pro. A 1-meter cable is available for $25, while a 2-meter version costs $35.
Few if any third-party Lightning to USB-C cables authorized under Apple's MFi Program are currently available.
Tip: An alternative option is to purchase a USB-C adapter or hub with at least one USB-A port and then use a traditional Lightning to USB cable — see below.
USB-C to USB Adapter — $19
This adapter allows you to connect the new MacBook Pro to standard USB accessories such as keyboards, wired mice, flash drives, cameras, printers, docks, and more. USB 3.0 speeds.
This adapter can also be paired with a Lightning to USB cable to charge and sync an iPhone, iPad, or iPod touch.
Tip: Satechi sells a cheaper USB-C to USB adapter for $14.99 in gold, silver, and space gray. USB 3.0 speeds. Monoprice has one for an even cheaper $8.99.
This adapter allows you to connect the new MacBook Pro to an HDMI display or TV in up to 1080p at 60Hz or Ultra HD (3,840 by 2,160 pixels) at 30Hz.
The adapter also has a USB-C port for pass-through charging, and a USB-A port for connecting a standard USB device such as a flash drive, camera, or sync cable.
Tip: Apple sells a similar USB-C VGA Multiport Adapter with VGA instead of HDMI for $69. Want just VGA? Belkin has a $40 adapter.
